IPC: F02B23/02
Filed: 1994-12-22
Abstract: PURPOSE: To provide a direct injection type diesel engine, wherein reduction of a thermal load and reduction of a weight are enabled by the piston of an OSKA-D and collision dispersion is enabled CONSTITUTION: A main combustion chamber 1 is provided around a cylinder head 16 which is faced to the inside of a cylinder, a squish area 2 is formed on the inner wall of a cylinder head 16 other than the main combustion chamber 1, a collision surface 3 and the edge 4 thereof are projected on the side surface of the main combustion chamber 1, and the collision surface 3 is set so that fuel jet to be splashed from the edge 4 is fed into the main combustion chamber 1 to be formed near the squish area 2. Fuel jet which is splashed by collision is dispersed by squish flow and reverse squish flow so as to reduce the amount of smoke. Since the main combustion chamber 1 is not manufactured on a piston upper surface 19, the weight of the piston is reduced, and also the heat receiving area of the piston is reduced.

When a valve 29 is opened at that time, refrigerant vapor generated in the high-temperature generator 13 is flowed mainly to the low-temperature generator 14 side of the high-pressure stage refrigerator. Refrigerant vapor generated in the high-temperature generator 13 is flowed mainly to the low-temperature generator 14 side of the high-pressure stage refrigerator when cooling water 25 is introduced to an internal condenser 12 by a valve 31, and refrigerant vapor is flowed through the intermediate-temperature generator side 4 of the low-pressure stage refrigerator when cooling water 25 is not introduced to the internal condenser and is bypassed 32. The heat source is applied to the high-temperature generator 13 at a high pressure stag and the heat source is not applied to the intermediate-temperature generator 4 of the low-pressure stage refrigerator on triple effect operation. The intermediate-temperature generator 4 of the low-pressure stage refrigerator receives a refrigerant from the high-pressure stage high-temperature generator 13, and works the refrigerant as an external condenser at a high-pressure stage.

Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To eliminate via resistor defects and to increase reliability in using a low permittitivity film for increasing an operating speed of a semiconductor integrated circuit, by involving at least a chemical mechanical polishing step in part of a resist removing step during processing of a through-hole of an interlayer film, having in part thereof an insulating film whose quality is changed by an oxygen plasma. SOLUTION: A photoresist 107 is processed, and then a through-hole 108 is formed by etching using a fluorocarbon-based gas and the photoresist 107 as a mask. At this time, the photoresist is damaged through etching and remains as a resist hardened layer 109. Through a slurry containing alumina is used for chemical mechanical polishing. The chemical mechanical polishing is used to remove the layer 109. Since a process for exposing a residual 111 of the resist and immersing the residual 111 into a developing solution is involved in some cases, connecting metal resistor defects do not occur.

Title: Image forming device
Inventor: HYODO FUMITAKA
IPC: G03G15/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To shorten processing time without exerting adverse effect on an image and to miniaturize the device by constituting the surface of a guide plate guiding the carrying direction of an output medium of a continuous smooth surface coming in surface-contact with the image surface of the output medium. SOLUTION: Two guide plates 67a and 67b are arranged to be opposed to each other on the downstream side of a driving roller 63 and a carrying roller 65 in a paper ejection part 61. At least the areas of the surfaces of the plates 67a and 67b, having possibility of coming in contact with recording paper, desirably, all the surfaces thereof are constituted of the even continuous smooth surface coming in surface-contact with the image surface of the recording paper. Since the image surface of the recording paper comes in surface-contact with the surfaces of the plates 67a and 67b, contact resistance is not concentrated at the limited part of the image surface and is dispersed, whereby the peeling or the soiling of the image hardly occurs.  Therefore, what is called a straight part need not be provided for the purpose of cooling after thermal fixing, because the recording paper is carried in a high-temperature state while changing its direction in a state where it is brought into contact with the plates 67a and 67b in the paper ejection part.

Abstract: PROBLEM TO BE SOLVED: To designate an area to be designated with excellent operability and at high speed by performing the control at the time without an original when an original detection signal is masked by a manual input means. SOLUTION: When a mask key 33 is depressed, whether a flag f mask combining the detection of the edge of the key with the latch of a mode is set or not is judged. When the mask is set, no processing is performed. When the mask is not set, it is judged that a mode is shifted to a mask mode, the flag f sensor combining the detection of the edge of the key to be set at the time of depressing a sensor key 31 and with the latch of the mode is reset, a sensor display is turned off, an f mask is set and a mask display is turned on. When the jam display related to an original exists or not is checked, and if a jam exists, the jam is released.  Thus, when whether an original detection signal is masked or not is manually inputted from the outside and the original detection signal is masked, the control at the time without the original is performed, regardless of the presence or absence of the original.

Abstract: PROBLEM TO BE SOLVED: To heat an object to be heated appropriately in accordance with the condition of it by a method wherein the vibration of a plate is detected to control a heating means by the signal. SOLUTION: The vibration of a bottom surface plate 2, which is generated by putting a matter 3 to be heated, is detected by a vibration sensor 4 through a supporting rod 5 to obtain the frequency (f) of vibration by an opening unit 6. The frequency (f0), obtained at the time when nothing is put on the bottom surface plate 2, is stored previously in an operating unit 6 to compare the frequency (f0) of vibration with the frequency (f) of vibration. The frequencies (f), (f0), have the same modulus of elasticity whereby the difference of masses, or whether an object 3 to be heated is put on the bottom surface plate 2 or not is detectedby comparison and the operating unit 6 outputs a control signal 7 to the control unit 7. When a user inputs the starting signal for heating, for example the control unit 7 operates a heating unit 8 when the signal of putting of an object to be heated is stored while the heating unit 8 is not operated when the signal is not stored in the control unit 7. By this constituted, the condition of the matter to be heated can be recognized, and the control of heating can be effected.
